Applicationfiled February 9, 1915, Serial No. 7,098. Renewed 'MarchS1917. serialNo. 153,461.

To all whom it may concern Be it known thatI, Earn. ANnnnsoN, a citizenof the United States 011 2111181108, and

a resident of Yonkers,county,of iVestchester, and State of New York,have invented ,1

certain new and useful Improvements in Turbine-Engines, ofwliich thefollowing is..-

a specification, reference being had to the accompanying drawings,forming a part thereof.

My invention relates to turbine engines and has special reference tosuch as are driven by an eXpansible motive fluid such as steam.

This invention pertains to engines of the same general character as thatset forth and described in my copending application, Serial No. 724,516,filed October 8, 1912, and patented Dec. 19, 1916, No. 1,208,888, andhas for one of its objects to provide an improved engine of this kindwhich is capable of developing its power efiiciently.

Other objects and advantages of my invention will be set forthhereinafter and in 'order that my invention may be thoroughly understood1 will now describe the same in the following specification and thenpoint out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a sectional side elevation of an engine which embodies myinvention.

Fig. 2 is a detail view of a portion of the rotor of the same machinedrawn to a larger scale.

A transverse sectional elevation of the rotor is shown in Fig. 3.

Fig. 4 is a sectional elevation of a portion of a slightly modifiedengine structure which also embodies my invention.

Corresponding parts are designated by the same reference characters inall of the figures.

The engine of Figs. 1, 2 and 3 comprises an annular frame 10 forming apart of the stator of the machine, nozzle sections 11, only one of whichis shown in detail, and a rotor structure 12.

The nozzle 11 comprises a hollow sector having an inlet opening 13 and aplurality of inclined discharge openings 1%, which are formed by vanesor spacers 15.

The rotor structure 12 comprises a disk or plate16 to whi'chis secured arotor 17. This ,rotor: is composed of a pair of annular, plates 18'whichare spaced-apart by multisection curved bucket'spacers 19. Each of thesespacers, as clearly shown in Fig. 2, has a relativelyshort radius bendat 20' nearthe discharge end of the rotor.

Between the spacer sections are a plurality of wavy disks 21 which aresubstantially parallel to the annular plates 18. The spacers and disksare riveted togetherand to the annular plates although some other meansmay be employed for making them into a unitary structure.

WVhile the disks 21 are corrugated transversely to form wavy passagesbetween them as in my co-pending application to which reference hasalready been made, they differ from the disks in my previous inventionby reason of the fact that they are notched or cut back to leave thespace adjacent to the short radius bends of the buckets unobstructed andundivided.

The structure of Fig. 1 is similar to that of the previous figures,except that small auxiliary buckets 22 are provided between the buckets19.

The operation of the machine will be understood from the description ofthe device, steam being admitted through the intake opening 13 into thehollow chambers of the nozzle sectors, is then discharged through theoutlet openings 1% and passes through the passages which aretransversely wavy near their intake ends and are curved backwardly neartheir outer ends.

The steam is compelled to do work upon the rotor in going through thewavy portion of the passage and produces the desired rotation. The shortradius bend of the buckets turns the steam backwardly and takes up theremainder of the force of the steam due to its velocity.

The corrugated disks are cut away adja cent to the bend in the bucketsin order that the entire force may be applied to the bucket with a viewto increasing the efiiciency of the machine.

The engine is effectively operative with but a single nozzle, but aplurality of nozzle sections will usually be employed.

Structural modifications may be efiected within the spirit and scope ofmy invention, and I intend that only such limitations be imposed as areindicated in the appended claims.

What I claim is:

1. A. turbine rotor comprising a pair'of spaced annular plates,interposed buckets tially parallel Wavy vanes interposedbe tween thebucket spacers near their intake end and cut away adjacent to the shortradius bend of the bucket spacers.

3. A turbine engine comprising a rotor having a plurality of buckets andmeans for providing a plurality of transverse fluid passages between thebuckets adapted to produce a plurality of parallel wavy paths adjacentto the intake end of the buckets and means for passing motive fluidthrough said buckets. V

In testimony whereof I have hereunto set my hand this lst day ofFebruary, 1915 in the presence of two subscribing witnesses.
